ADUM3402WBRWZ-RL

Overview

The ADUM3402WBRWZ-RL is a quad-channel digital isolator manufactured by Analog Devices Inc., utilizing iCoupler magnetic coupling technology. It features four bidirectional channels with a data rate of 90 Mb/s and an isolation voltage of 2500 Vrms. The device operates on a supply voltage range of 2.7 V to 5.5 V, drawing a typical operating current of 136 mA. Key electrical parameters include a propagation delay of 32 ns, rise/fall times of 3 ns, and a pulse width of 1000 ns. It functions within a temperature range of -40°C to +105°C and is housed in a 16-SOIC package.

Feature Summary

• Integrates four independent bidirectional digital communication channels within a single compact package.
• Employs iCoupler magnetic coupling technology for signal transmission across isolation barriers.
• Provides robust common-mode transient immunity to protect against high-speed noise interference.
• Supports standard logic interface levels without requiring external biasing components.

Applications

• Industrial automation systems requiring isolated sensor interfaces
• Power electronics control circuits for motor drives
• Medical equipment needing galvanic isolation for safety compliance
• Data acquisition systems with mixed-signal ground separation

Procurement Notes

Verify the specific suffix WBRWZ-RL to confirm the reel packaging format and tape width specifications. Ensure the component meets AEC-Q100 qualification requirements if automotive reliability standards are mandatory for the application. Cross-reference the datasheet revision date to confirm the accuracy of timing parameters before finalizing the bill of materials.

Selection Notes

Select this component when bidirectional communication is required across a 2500 Vrms barrier at speeds up to 90 Mb/s. Compare power consumption against unidirectional alternatives if system efficiency is critical. Confirm that the SOIC-16 footprint aligns with existing PCB layout constraints and thermal management strategies for the target operating environment.

Part Context

This part belongs to the ADUM3402 series of quad digital isolators from Analog Devices. It complements other variants like the ADUM3400 and ADUM340E1 by offering a balance between speed and power consumption. The series utilizes proprietary silicon-on-insulator technology to create integrated isolation barriers directly on the semiconductor die.
